As a child your parents teach you the difference between good and bad decisions. They wait behind you and give you a choice: one bad and one good. When you choose the bad they swoop in and chastise you for picking the wrong one and if you pick the right one they explode overjoyed at your selection. From a psychological standpoint this is called operant conditioning where they use positive and negative reinforcement along with their own ideas of good and bad. This portion of parenting is designed to give you basic decision-making skills and keep you alive and whole to learn enough to develop your own value system and make informed decisions.
As young adults we try to adapt those ideas we were taught as toddlers to the world at large and soon we realize that there is no black and white; that nothing is so simple as what was used to teach you. As an adult, no decisions are wrong or right, but rather decisions have consequences and you have to decide if your goal or your desire for achieving that goal justifies the risk present in the consequences.
